Abstract
Binocular and monocular finger reaction times were measured for circular broad-band stimuli for natural and artificial pupils. Luminance polarity changes were presented at the fovea respect to a reference stimulus under suprathreshold conditions. As in previous studies, binocular reaction times were shorter than monocular with both pupil types. Nevertheless, this binocular summation effect was less marked with the artificial case, becoming more pronounced for dark variations. These result suggest that the near- responses mechanism at the peristriate area of the occipital and at the inferior parietal lobe could support an important role on luminance interactions within the visuomotor pathway.
